WHERE IS US ATOMIC CLOCK LOCATED?

US Atomic clock is located at Fort Collins outside Boulder, Colorado, and is operated by the US Government.

WHERE ARE THE ATOMIC CLOCKS LOCATED AROUND THE WORLD?

There are several Atomic Clocks operated in other countries such as Germany, Switzerland, United Kingdom and Japan.

WHERE CAN I USE MY ATOMIC TIME KEEPING DEVICE?

Most of the Atomic Clocks can be used within the continental United States (CONUS).   There is the exception of the multi-band travel devices which can be used outside of the United States.

WILL MY ATOMIC TIME KEEPING DEVICE WORK IN DIFFERENT CONTINENTS AROUND THE WORLD?

Only the model RC304EL (Digiview Multi-Band Travel Alarm Clock) will work outside of the North American continent. It will synchronize its time to the Atomic Clocks time located in Europe, North America and Japan.  All other clock models are the US Atomic clocks and will synchronize time with the US Atomic Clock located in Boulder, Colorado.

WILL MY ATOMIC TIME UNIT WORK IN ALASKA AND HAWAII?

If used in Alaska and Hawaii, the Atomic clocks will not receive the RF signal from the US Atomic Clock during the normal daylight hours. The 50kW radio signal transmitted at 60 kHz frequency covers the Continental United States (CONUS) and reaches parts of Alaska and Hawaii during the night-time hours.  However, all clocks can be set manually if the signal from Boulder, Colorado is not able to reach the locations that geographically are not in the US Atomic Clock Time Signal coverage area.

WHERE I CAN FIND THE US ATOMIC CLOCK SIGNAL COVERAGE MAP?

The US Atomic Clock coverage map can be retrieved from the NIST website by clicking the following link:

WILL MY ATOMIC CLOCK WORK IN CANADA AND MEXICO?

Atomic Clocks purchased in the United States are pre-set to the radio signals broadcasted by the United States Atomic Clock located near Boulder, Colorado. The coverage area of these signals is able to reach only limited areas beyond the US borders.

The areas for Canada provinces corresponding to the United States Time Zones as follow:

British Columbia, Yukon Territory – Pacific Standard Time

Alberta, Northwest Territory – Mountain Standard Time

Manitoba, Nunavut – Central Standard Time

Ontario, Quebec – Eastern Standard Time

The areas for Mexico corresponding to the United States Time Zones:

North Baja Peninsula – Pacific Standard Time

South Baja Peninsula, Central and Western Mexico - Mountain Standard Time

Coahula, Nuevo Leon, Durango, Zacatecas, Tamaulipas, San Luis Potosí, Veracruz, Jalisco, Colima, Michoacán, Guerrero, Oaxaca – Central Standard Time

Tabasco, Chiapas, Campeche, Yucatán, Quintana Roo – Eastern Standard Time.

HOW LONG THE PROJECTION WILL STAY ON?

It depends on the power requirements for the projection device you own. Your product is able to project the specified image for a short period of time (5-6 seconds), or continuously (when the AC/DC adapter is connected). Some projection devices are designed to project the image just for a short period of time.

HOW DO I SET THE US TIME ZONE ON MY ATOMIC CLOCK?

1. Press MODE button selecting the “Time with the Day of the Week” display mode.

2. Select the Time Zone by pressing and holding the “▲” or “UP” button for 3 seconds.

3. Keep holding “▲” or “UP” button until the desired US Time Zone (Pacific, Mountain, Central or Eastern) is highlighted on the display map.

4. Press MODE to confirm the selected US Time Zone.

WHAT IS “PROGRAMMABLE SNOOZE INTERVAL” MEANS?

Some of the products have great features such as a programmable snooze interval.

The user is able to program the clock’s snooze time for different time intervals – from 0 to 59 minutes after the alarm.

HOW LONG THE BATTERIES LAST IN THE UNIT?

The average battery life in the atomic time keeping device is 12 months. 

HOW TO INTERPRET THE MOON PHASE ICON?

From any location on the Earth, the Moon appears as circular disk illuminated by direct sunlight. Like the Earth, the Moon is a sphere which is always half illuminated by the Sun.   As the Moon orbits the Earth, we get to see more or less of the illuminated half. During each lunar orbit (a lunar month), we see the Moon's appearance change from not visibly illuminated through partially illuminated to fully illuminated, then back through partially illuminated to not illuminated again. Although this cycle is a continuous process, there are eight distinct, traditionally recognized stages, called phases. The phases designate both the degree to which the Moon is illuminated and the geometric appearance of the illuminated part. These phases of the Moon, in the sequence of their occurrence (starting from New Moon), are listed below:
